1 r y y This invention relates to a closure operator andit is an object of the invention to provide :an

operator of this kind for use in connection with '4 Claims. (01. ass-129;)

two relatively .movable members and wherein means are provided for locking said means in different relations. a

It is also an object of the. invention :to pro- 'vide .an operator wherein desired opening" and closing movements may be obtained by the turning of .a shaft and wherein :means are associated with the shaft for locking a closure member "or members in difierent positions/between iully opened andfully closed. i

The invention consists in the details of construction and in the combination and arrangement of the several'parts (of my improved closure operatorwhereby certain advantages are attainedas will be hereinafter more fully setforth.

In order that my invention may be better understmdlwill. nowproceed to describethe same with reference to the accompanying drawings, wherein:

figure l is a fragmentary viewsin front elevation illustrating a closure operator constructed in accordance with an embodiment of the invention and employed inconnection with upper ,andlower sashes cil a window structure;

portion oftheplate 9. e sleeve 8'snugl y fits W 'from without in the opening 2 through the inside 'wall I of the stile S and the plate 9 is secured by the screw l-Oor the like, to the outer face i of said inside wall I. i

"The inner or opposed ends of the sleeve drums 6 and 1 are providedin their walls with the outwardly opening recesses H and l2, respectively,

which are adapted tobe brought intoregister for a purpose to be hereinafter explained. Extending through thesleeve I and into the sleevefi is an endwise movable shaft H having one end portionextending through the opening IS in the plate 9 and outwardly beyondthe inside wall l of the stile. The extended portion of the shaft H! has operativelyengaged therewith a crank l6 s to provide ameans for rotatingthe same as desired in either direction.

'Theshaft I4 is provided with an outwardly and radiallydisposedblade or key I 1' which is normally heldwithinthe recess I2 of the" sleeve 1 by an expansible member 18. This member 18 is herein disclosed'as comprising a coil spring encircling the shaft l4 and interposed between Figure 2 is an enlarged detail sectional view 7 taken substantially on the line 2-"-2 of Figure '1;

Figure 3 is a detail sectional view taken substantially on the line 3-3 of Figure 2, the stile being omitted; and

Figure 4 is an enlarged detail sectional view taken substantially on the line 4-4 of Figure3.

As illustrated in the accompanying drawings,

S denotes a conventional type of stile for a window in which are arranged the usual balance weight for the upper sash A and the lower sash B. A these are all well known a detaildescription and illustration thereof is believed unnecessary.

The sidewalls I of the stile tions are provided with the aligned openings 2. Secured by the screws 3 or thelilre,v to the outer face of the outside wall I of the stile S, is a plate 4,-of a socket member S, which is disposed over the opening 2. v The central portion of the plate W 4 has rigid therewith a sleeve 5 which snugly fits within the opening 2 of the outside wall I and serves as a bearing to rotatably support one end portion of a drum sleeve 6.

The drum sleeve 6 is aligned with a second S at desired locaan outwardly facing internal shoulder I'll" within the sleeve 1 and the extended extremities "of a pin 2lldisposed radially through the shaft H at a desired distance outwardly from the internal shoulder I9. This pin 20 bycontact from within with the plate 9 provides'a means to limit the extent of outward movement of the shaft Haas will also the blade or key l1. j 1

Tightly winding around the drum sleeve 1' is the intermediate portion of fafiexible cable 2| one end portion of which extending upwardly and out through the toppart of the front wall-'22 of the stile s over a conventional pulley 23; "The cable extends downwardlyfrom the pulley 23 and is anchored, at 24 to the top rail 240:0! the bottom sash'B. The cable 2| has a portion extending downwardly from the sleeve drum 1 and out through the front wall 22 of the stile S in engagement with a conventional pulley 26. The

cable extends upwardly from this pulley 2G and is anchored, as at 21, to the lower portion of the adjacent side rail 28 of the lower sash B. By

this arrangement, turning the sleeve drum Tin one direction will raise the lower sash'B and ;said sash will be returned upon reverse rotation drum sleeve 1, the outer end portion of which is rotatably supported in a second socket member S" comprised in a sleeve 8 rigid with the central 01 the drum sleeve 1.

Tightly engaged with the sleeve drum 6 is an intermediate portion of a flexible cable 29. A portion of the cable 29 extends upwardly and y The drum sleeve 1 will only be rotated in either direction whilethe blade" l ,The end portion. of the sleeve drum theibearing sleeve 5 is provided with a longitudi' S in engagement with a conventional pulley 34 preferably "to' one side of the pulley 26, hereinbefore referred to.

Upon desired rotation of the'sleeve drum 6; f

the upper sash A will be either-raised or lowered and it is believed to be obvious that the required rotation of the sleeve drum 6 can only be eifected when the key or blade [1 is within the recess I I of the sleeve drumlii; This positioning of the blade-or key ll within therecess II is obtained by forcing inwardly the shaft l4 and which movement of the shaft will compress the member or spring I8 to place the same under such tension to assure automatic return of the blade or key .V I1! into therecess lZof the sleeve drum 1 while the=shaftshi is relieved ofpressure.
